This episode references other AIO episodes, such as "A License to Drive" and "Truth, Trivia, and 'Trina." There are also some spoofs, such as "Malachi's Message" with the scene about Tom meeting an angel named Haggai, and the scene with Dr. Blackgaard's appearance, which is a reference to "Blackgaard's Revenge." This episode also contains many in-jokes for fans, like Connie remaining 16 for a while and Eugene and Katrina's "long, drawn-out, seemingly never to end engagement."
